MELAS Missed for Years: Stroke-Like Lesions Are No Indication for Brain Biopsy

Figure 1

Cerebral MRI, 2 months after onset of psychosis, epilepsy, and visual impairment showing a slightly hyperintense right occipital lesion and a slightly hypointense similar lesion in the left occipital area, which were both hyperintense on ADC and hyperintense on T2-weighted images. Within the right occipital lesion, cortical and subcortical bleeding was identified. The occipital lesions were retrospectively interpreted as consecutive, subacute SLLs.
